Grr. Rather I didn't see a reply when I asked about it.  I just
spotted Suka's old reply telling me it was to attempt to prevent
init from getting sigio.    Clearly I have a big fat blind spot
here you could drive a truck through.

Kernel generated signals are a pain because they are neither fish nor
fowl. They are sent privileged, but we don't necessarily want to give
them all curtsies and deliver them.  Grr.
